What type of machine typically uses milling cutters?

Milling cutters are specifically designed to be used with milling machines, which are tools that rotate the cutters to remove material from a workpiece. This process allows for the shaping, contouring, and finishing of various materials, including metals and plastics, through the controlled motion of the cutter against the stationary workpiece. The design and functionality of milling cutters enable them to perform a variety of operations, such as face milling, side milling, and slotting, which are essential tasks that milling machines are specifically engineered to perform.

In contrast, drilling machines primarily use drill bits to create cylindrical holes, turning machines focus on rotating a workpiece against cutting tools for shaping, and grinding machines use abrasives for surface finishing rather than cutting with sharp edges like milling cutters. Thus, the unique relationship between milling cutters and milling machines is what makes milling machines the correct answer in this context.
